AFA I know, this is the industry standard. Mine's actually a flat 4, so this is the best I can help. From the GY6 manual: Attachments:

From the GY6 manual: Apparently that manual is wrong, at least for the majority of scooters including the one it was written for. tinyurl.com/23wb5p6 As far as an industry standard goes I found no less than four different pinouts for this regulator before I gave up looking for more. The bottom line is you have to know what the pin outs are for the particular regulator you are installing. |

I guess I "knew" wrong. That's fine; I'm happy to learn this now.
If you have an ohm meter, use the testing diagram in your link. With a bit of logic, you should be able to determine the correct pinout.

With a bit of logic, you should be able to determine the correct pinout. I've been there and done that, to all 4 pinouts examples that I've found. The results are that any one of the pinouts, with the exception of the one in the manual, could conceivably pass the test. This means I'm still left with 3 different ways it could be hooked up. |

If you map out your resistances with a blank chart similar to the manual but only using 1,2,3,4 as labels and ignore existing pinout charts, you should come out with only 1 possible pinout.
Edit:
Rules to follow:
White and Red will show resisted continuity in ONE direction only. Red will be the positive lead on the meter.
Yellow and Green show resisted continuity in both directions. This then is down to determining which is which....
According to abscooters, green is diagonal from red. This should lock in the pin set.

I found the correct pinouts by systematically and cautiously testing the AC and DC circuits separately. Here's what worked-  Apparently the meter impedance is very important to getting the indicated resistance ranges on the chart. Instead of getting 2.4 to 7 K ohms I got 7 to 10 megohms except for the red (-) to white (+) where I got 140K ohms. None the less the regulator worked correctly and within allowable voltages once connected properly. In case you're wondering what's inside here's a schematic that Lynn Edwards went thru the trouble of making when dissecting one,  |

That is a far more complicated schematic than the one I saw out of the Honda manual, and one that reflects what I'd hope to see in one of these things (full phase). Unfortunately, this diagram does fail to address how AC2 (Yellow) is regulated from blowing your lights and thus I cannot accept that this is what is in my scooter. The diagram from the Honda common service manual (half-phase regulator with dump against AC2) makes much more sense with the behavior that I have observed from my scooter. Attachments:
